2 Testlet 1 Overview VanArsdel, Ltd. builds skyscrapers, subways, and bridges. VanArsdel is a leader in using technology to do construction better. Overview VanArsdel employees are able to use their own mobile devices for work activities because the company recognizes that this usage enables employee productivity. Employees also access Software as a Service (SaaS) applications, including DocuSign, Dropbox, and Citrix. The company continues to evaluate and adopt more SaaS applications for its business. VanArsdel uses Azure Active Directory (AD) to authenticate its employees, as well as Multi-Factor Authentication (MFA). Management enjoys the ease with which MFA can be enabled and disabled for employees who use cloud-based services. VanArsdel's on-premises directory contains a single forest. Helpdesk: VanArsdel creates a helpdesk group to assist its employees. The company sends messages to all its employees about the helpdesk group and how to contact it. Configuring employee access for SaaS applications is often a time-consuming task. It is not always obvious to the helpdesk group which users should be given access to which SaaS applications. The helpdesk group must respond to many phone calls and messages to solve this problem, which takes up valuable time. The helpdesk group is unable to meet the needs of VanArsdel's employees. However, many employees do not work with the helpdesk group to solve their access problems. Instead, these employees contact their co-workers or managers to find someone who can help them. Also, new employees are not always told to contact the helpdesk group for access problems. Some employees report that they cannot see all the applications in the Access Panel that they have access to. Some employees report that they must re-enter their passwords when they access cloud applications, even though they have already authenticated. Bring your own device (BYOD): VanArsdel wants to continue to support users and their mobile and personal devices, but the company is concerned about how to protect corporate assets that are stored on these devices. The company does not have a strategy to ensure that its data is removed from the devices when employees leave the company. Customer Support VanArsdel wants a mobile app for customer profile registration and feedback. The company would like to keep track of all its previous, current, and future customers worldwide. A profile system using third-party authentication is required as well as feedback and support sections for the mobile app. Migration: VanArsdel plans to migrate several virtual machine (VM) workloads into Azure. They also plan to extend their on-premises Active Directory into Azure for mobile app authentication. Business Requirements Hybrid Solution: A single account and credentials for both on-premises and cloud applications Certain applications that are hosted both in Azure and on-site must be accessible to both VanArsdel employees and partners The service level agreement (SLA) for the solution requires an uptime of 99.9% The partners all use Hotmail.com addresses Mobile App: VanArsdel requires a mobile app for project managers on construction job sites. The mobile app has the following requirements: The app must display partner information. The app must alert project managers when changes to the partner information occur. The app must display project information including an image gallery to view pictures of construction projects. Project managers must be able to access the information remotely and securely.

3 Security: VanArsdel must control access to its resources to ensure sensitive services and information are accessible only by authorized users and/or managed devices. Employees must be able to securely share data, based on corporate policies, with other VanArsdel employees and with partners who are located on construction job sites. VanArsdel management does NOT want to create and manage user accounts for partners. Technical Requirements Architecture: VanArsdel requires a non-centralized stateless architecture fonts data and services where application, data, and computing power are at the logical extremes of the network. VanArsdel requires separation of CPU storage and SQL services Data Storage: VanArsdel needs a solution to reduce the number of operations on the contractor information table. Currently, data transfer rates are excessive, and queue length for read/write operations affects performance. A mobile service that is used to access contractor information must have automatically scalable, structured storage Images must be stored in an automatically scalable, unstructured form. Mobile Apps: VanArsdel mobile app must authenticate employees to the company's Active Directory. Event-triggered alerts must be pushed to mobile apps by using a custom Node.js script. The customer support app should use an identity provider that is configured by using the Access Control Service for current profile registration and authentication. The customer support team will adopt future identity providers that are configured through Access Control Service. Security: Active Directory Federated Server (AD FS) will be used to extend AD into Azure. Helpdesk administrators must have access to only the groups of Azure resources they are responsible for. Azure administration will be performed by a separate group. IT administrative overhead must be minimized. Permissions must be assigned by using Role Based Access Control (RBAC). Line of business applications must be accessed securely. QUESTION 1 You need to assign permissions for the Virtual Machine workloads that you migrate to Azure. The solution must use the principal of least privileges. What should you do? A. Create all VMs in the cloud service named Groupl and then connect to the Azure subscription.

9 Testlet 1 Background Overview Trey Research conducts agricultural research and sells the results to the agriculture and food industries. The company uses a combination of on-premises and third-party server clusters to meet its storage needs. Trey Research has seasonal demands on its services, with up to 50 percent drops in data capacity and bandwidth demand during low-demand periods. They plan to host their websites in an agile, cloud environment where the company can deploy and remove its websites based on its business requirements rather than the requirements of the hosting company. A recent fire near the datacenter that Trey Research uses raises the management team's awareness of the vulnerability of hosting all of the company's websites and data at any single location. The management team is concerned about protecting its data from loss as a result of a disaster. Websites Trey Research has a portfolio of 300 websites and associated background processes that are currently hosted in a third-party datacenter. All of the websites are written in ASP.NET, and the background processes use Windows Services. The hosting environment costs Trey Research approximately S25 million in hosting and maintenance fees. Infrastructure Trey Research also has on-premises servers that run VMs to support line-of-business applications. The company wants to migrate the line-of-business applications to the cloud, one application at a time. The company is migrating most of its production VMs from an aging VMWare ESXi farm to a Hyper-V cluster that runs on Windows Server Applications DistributionTracking Trey Research has a web application named Distributiontracking. This application constantly collects realtime data that tracks worldwide distribution points to customer retail sites. This data is available to customers at all times. The company wants to ensure that the distribution tracking data is stored at a location that is geographically close to the customers who will be using the information. The system must continue running in the event of VM failures without corrupting data. The system is processor intensive and should be run in a multithreading environment. HRApp The company has a human resources (HR) application named HRApp that stores data in an on-premises SQL Server database. The database must have at least two copies, but data to support backups and business continuity must stay in Trey Research locations only. The data must remain on-premises and cannot be stored in the cloud. HRApp was written by a third party, and the code cannot be modified. The human resources data is used by all business offices, and each office requires access to the entire database. Users report that HRApp takes all night to generate the required payroll reports, and they would like to reduce this time. MetricsTracking Trey Research has an application named MetricsTracking that is used to track analytics for the DistributionTracking web application. The data MetricsTracking collects is not customer-facing. Data is stored on an on-premises SQL Server database, but this data should be moved to the cloud. Employees at other locations access this data by using a remote desktop connection to connect to the application, but latency issues degrade the functionality. Trey Research wants a solution that allows remote employees to access metrics data without using a remote desktop connection. MetricsTracking was written in-house, and the development team is available to make modifications to the application if necessary. However, the company wants to continue to use SQL Server for MetricsTracking. Business Requirements

35 Testlet 1 Background Overview Northwind Electric Cars is the premier provider of private, low-cost transportation in Denver. Northwind drivers are company employees who work together as a team. The founding partners believe that by hiring their drivers as employees, their drivers focus on providing a great customer experience. Northwind Electric Cars has a reputation for offering fast, reliable, and friendly service, due largely to their extensive network of drivers and their proprietary dispatching software named NorthRide. Northwind Electric Cars drivers depend on frequent, automatic updates for the NorthRide mobile app. The Northwind management team is concerned about unplanned system downtime and slow connection speeds caused by high usage. Additionally, Northwind's in-house data storage solution is unsustainable because of the new influx of customer data that is retained. Data backups are made periodically on DVDs and stored onpremises at corporate headquarters. Apps NorthRide App Northwind drivers use the NorthRide app to meet customer pickup requests. The app uses a GPS transponder in each Northwind vehicle and Bing Maps APIs to monitor the location of each vehicle in the fleet in real time. NorthRide allows Northwind dispatchers to optimize their driver coverage throughout the city. When new customers call, the dispatcher enters their pickup locations into NorthRide. NorthRide identifies the closest available driver. The dispatcher then contacts the driver with the pick-up details. This process usually results in a pick-up time that is far faster than the industry average. Drivers use NorthRide to track the number of miles they drive and the number of customers they transport. Drivers also track their progress towards their established goals, which are measured by using key performance indicators (KPIs). NorthRide App 2.0 Northwind Electric Cars is growing quickly. New callers often wait for their calls to be answered because the dispatchers are contacting their drivers to arrange pickups for other customers. To support the growth of the business, Northwind's development team completes an overhaul of the NorthRide system that it has named NorthRide 2.0. When a dispatcher enters a customer's pickup location, the address and driving directions are automatically sent to the driver who is closest to the customer's pickup location. Drivers indicate their availability on the NorthRide mobile app and can view progress towards their KPI's in real time. Drivers can also record customer ratings and feedback for each pickup. Business Requirements Apps NorthRideFinder App Northwind Electric Cars needs a customer-facing website and mobile app that allows customers to schedule pickups. Customers should also be able to create profiles that will help ensure the customer gets a ride faster by storing customer information. Predictor App Northwind Electric Cars needs a new solution named Predictor. Predictor is an employee-facing mobile app. The app predicts periods of high usage and popular pickup locations and provides various ways to view this predictive data. Northwind uses this information to better distribute its drivers. Northwind wants to use the latest Azure technology to create this solution. Other Requirements On-premises data must be constantly backed up. Mobile data must be protected from loss, even if connectivity with the backend is lost.

36 Dispatch offices need to have seamless access to both their primary data center and the applications and services that are hosted in the Azure cloud. Connectivity needs to be redundant to on-premises and cloud services, while providing a way for each dispatch office to continue to operate even if one or all of the connection options fail. The management team requires that operational data is accessible 24/7 from any office location. Technical Requirements Apps and Website NorthRide / NorthRideFinder Apps: The solution must support on-premises and Azure data storage. The solution must scale as necessary based on the current number of concurrent users. Customer pickup requests from NorthRideFinder must be asynchronous. The customer pickup request system will be high in volume, and each request will have a short life span. Data for NorthRideFinder must be protected during a loss of connectivity. NorthRide users must authenticate to the company's Azure Active Directory. Northwind Public Website The customer website must use a WebJob to process profile images into thumbnails The customer website must be developed with lowest cost and difficulty in mind. The customer website must automatically scale to minimize response times for customers. Other Requirements Data Storage: The data storage must interface with an on-premises Microsoft SQL backend database. A disaster recovery system needs to be in place for large amounts of data that will backup to Azure. Backups must be fully automated and managed the Azure Management Portal. The recovery system for company data must use a hybrid solution to back up both the on-premises Microsoft SQL backend and any Azure storage. Predictive Routing: An Azure solution must be used for prediction systems. Predictive analytics must be published as a web service and accessible by using the REST API. Security: The NorthRide app must use an additional level of authentication other than the employee's password. Access must be secured in NorthRide without opening a firewall port. Company policy prohibits inbound connections from internet callers to the on-premises network. Customer usernames in NorthRideFinder cannot exceed 10 characters. Customer data in NorthRideFinder can be received only by the user ID that is associated with the data. QUESTION 1 You need to design the authentication solution for the NorthRide app. Which solution should you use? A. Azure Active Directory Basic with multi-factor authentication for the cloud and on-premises users. B. Active Directory Domain Services with mutual authentication C. Azure Active Directory Premium and add multi-factor authentication the for cloud users D.

42 Question Set 1 QUESTION 1 You are designing an Azure web application. The solution will be used by multiple customers. Each customer has different business logic and user interface requirements. Not all customers use the same version of the.net runtime. You need to recommend a deployment strategy. What should you recommend? A. Deploy with multiple web role instances. B. Deploy each application in a separate tenant. C. Deploy all applications in one tenant. D. Deploy with multiple worker role instances. Correct Answer: B /Reference: There are two types of tenant environments. The simplest type is a single-tenant application where one customer has 100% dedicated access to an application s process space. A single Tenant Applications has a separate, logical instance of the application for each customer or client. A single tenant application is much more predictable and stable by its nature since there will never be more than one dedicated customer at any point in time in that VM. That customer has all of its users accessing that dedicated instance of the application. Reference: Multi Tenancy and Windows Azure. Overview of Multi tenant Application and Single tenant Application Architectural considerations. QUESTION 2 You design an Azure application that processes images.

You need to recommend a DNS resource record type that will allow you to configure access to the web application by using a custom domain name. Which DNS record type should you recommend? A. SRV B. MX C. CNAME D. A Correct Answer: C /Reference: A CNAME record maps a specific domain, such as contoso.com or to a canonical domain name. In this case, the canonical domain name is the <myapp>.cloudapp.net domain name of your Azure hosted application. Once created, the CNAME creates an alias for the <myapp>.cloudapp.net. The CNAME entry will resolve to the IP address of your <myapp>.cloudapp.net service automatically, so if the IP address of the cloud service changes, you do not have to take any action. Incorrect: Not D: * Since an A record is mapped to a static IP address, it cannot automatically resolve changes to the IP address of your Cloud Service. * An A record maps a domain, such as contoso.com or or a wildcard domain such as *.contoso.com, to an IP address. In the case of an Azure Cloud Service, the virtual IP of the service. So the main benefit of an A record over a CNAME record is that you can have one entry that uses a wildcard, such as *.contoso.com, which would handle requests for multiple sub-domains such as mail.contoso.com, login.contoso.com, or

The application includes services hosted in different geographic locations. The service locations may change. You must minimize the cost of communication between services. You need to recommend an approach for data transmission between your application and Azure services. The solution must minimize administrative effort. What should you recommend? A. Azure Table storage B. Service Bus C. Service Management API D. Azure Queue storage Correct Answer: B /Reference: The cost of ACS transactions is insignificant when performing messaging operations against Service Bus queues. Service Bus acquires one ACS token per a single instance of the messaging factory object. The token is then reused until it expires, after about 20 minutes. Therefore, the volume of messaging operations in Service Bus is not directly proportional to the amount of ACS transactions required to support these operations.

Install a secondary site underneath the primary site onto an Azure VM. Correct Answer: C /Reference: Cloud-based distribution Point, a Configuration Manager Site System Role in the Cloud Much of the Configuration Manager topology is made up of distribution points, they are very helpful in many situations where bandwidth and geographical separation are the facts of life, but also hard to manage if you have hundreds or even thousands of them. This feature started with the vision that it makes perfect sense to have big distribution points in the Windows Azure cloud where one should not worry about things like (but not limited to) size, performance, reliability, security, access from all around the world, hardware/software update issues etc. Note: Content management in System Center 2012 Configuration Manager provides the tools for you to manage content files for applications, packages, software updates, and operating system deployment. Configuration Manager uses distribution points to store files that are required for software to run on client computers. These distribution points function as distribution centers for the content files and let users download and run the software. Clients must have access to at least one distribution point from which they can download the files.
